Introduction

iPro2 system user safety assistance321

Welcome to iPro2 Continuous Glucose Monitoring (CGM)

Thank you for your trust in Medtronic products and services. We hope you will find iPro2 to be

the simplest and most convenient CGM product that you have ever used.

• This User Guide provides the information that you need for setting up and using the iPro2

CGM system.

• You will find a page like this at the beginning of each chapter. This page gives you a basic

overview of that chapter, and the steps you will take to complete each task.

• You will also see a “Key Notes” area on each chapter overview page. These are the important

points for you to remember from that chapter.

iPro2 CGM User Guide Introduction 1

iPro2 system

iPro2 DockiPro2 cleaning plug

Dock USB Cable

wall-powered adapter

These are the components of the iPro2 CGM system:

• iPro™2 digital recorder, MMT-7741 (iPro2)

The iPro2 collects and stores data from a glucose sensor. The data can be uploaded into

CareLink iPro™ Therapy Management Software for Diabetes (CareLink iPro, MMT-7340), to

generate reports and store the data. The iPro2 can collect up to seven 24-hour periods of

data, after which it shuts off automatically.

The iPro2 has an internal green light. This light flashes when you connect the iPro2

to an inserted glucose sensor. It will only flash if the iPro2 detects an adequately hydrated

sensor, is fully charged, and does not already contain any data.

• iPro™2 Docking Station, MMT-7742 (Dock)

The Dock has two main functions: charging the iPro2 and uploading data from the iPro2 to

CareLink iPro. The Dock has three lights to provide status information. The white Dock power

light indicates whether power is supplied to the Dock. When you connect the iPro2 to the

Dock, the green charging light and the red warning light indicate the status of the iPro2. If

the green charging light is on, the iPro2 is 100% ready to use.

In this User Guide, you will see the three Dock lights described using the following

conventions. Each light is always either off, on, or flashing.

!!

White Dock Power LightGreen Charging Light

Red Warning Light

OffOn

Flashing

• iPro™2 Dock USB cable (refer to MMT-7747 if re-ordering)

The small end of the Universal Serial Bus (USB) cable connects to the Dock. The other end

of the cable connects to a USB port on a computer, so that you can upload data into CareLink

iPro™ and charge the iPro2. You can also connect the USB cable to a wall-powered adapter.

• Wall-powered adapter (refer to MMT-7747 if re-ordering)


The wall-powered adapter lets you charge the iPro2 by connecting the Dock to a regular

electrical socket, instead of a computer.

The wall-powered adapter comes with four (4) interchangeable power plugs. Connect the

appropriate power plug to the wall-powered adapter.

• Three (3) iPro™2 Cleaning Plugs, MMT-7744 (cleaning plug)

The cleaning plugs provide a water-tight seal to protect the connector on the iPro2. Always

use a cleaning plug when cleaning and disinfecting the iPro2.

Do not clean the o-rings on the cleaning plug, as this can damage the o-rings.

The cleaning plug can be used to clean the iPro2 30 times. Keep track of cleaning plug uses

and discard the cleaning plug after 30 uses. If you continue to use the cleaning plug beyond

30 times, the iPro2 connector could be damaged, because the cleaning plug cannot continue

to provide a water-tight seal. You will also need the following:

• Serter, MMT-7500 or MMT-7510

• Glucose sensor, MMT-7002, MMT-7003 or MMT-7008

• A computer with Internet access to CareLink iPro, MMT-7340 (http://ipro.medtronic.com)

• Patient Log Sheet

• Patient Consent Form

• Patient Instructions Sheet

• Clinic Equipment Log Sheet

• Clinic Checklist (for patient setup and for uploading iPro2 data and printing reports)

• Occlusive adhesive dressing

User safety

This section includes important safety information such as indications, contraindications,

warnings, and precautions.

Indications for use

This iPro2 digital recorder is intended to continuously record interstitial glucose levels in persons

with diabetes mellitus. This information is intended to supplement, not replace, blood glucose

information obtained using standard home glucose monitoring devices. The information


http://ipro.medtronic.com

collected by the iPro2 digital recorder may be uploaded to a computer (with Internet access)

and reviewed by healthcare professionals. The information may allow identification of patterns

of glucose-level excursions above and below a desired range, facilitating therapy adjustments,

which may minimize these excursions.

This iPro2 system:

• is intended for prescription use only.

• does not allow data to be made available directly to patients in real time.

• provides data that will be available for review by physicians after the recording interval (144

hours).

• is intended for occasional rather than everyday use.

• is to be used only as a supplement to, and not a replacement for, standard invasive

measurement.

Contraindications

None known.

Warnings

• This product contains small parts and may pose a choking hazard for young children.

• The glucose sensor should be removed if redness, bleeding, pain, tenderness, irritation, or

inflammation develops at the sensor insertion site, or if the patient experiences unexplained

fever.

• An optional occlusive adhesive dressing should be removed if irritation or reaction to the

tape develops.

• The glucose sensor may create special needs regarding your patients' medical conditions or

medications. Healthcare professionals should discuss this with their patients before they use

the glucose sensor.

Precautions

• Do not expose the iPro2 to Magnetic Resonance Imaging (MRI) equipment, x-ray

equipment, Computed Tomography (CT) scanners, Intensity-Modulated Radiation Therapy

(IMRT), or other devices that generate strong magnetic fields or ionizing radiation. If the

iPro2 is inadvertently exposed to a strong magnetic field, discontinue use and contact your

local country representative.

• If performing multiple iPro2 studies on the same patient, establish a rotation schedule for

choosing new sensor sites.

• Avoid inserting a sensor in areas on the body that are constrained by clothing, have scar

tissue, or are subject to rigorous movement during exercise.

• If the Enlite™ sensor (MMT-7008) was inserted, wait five minutes before connecting the

iPro2. If a different sensor (MMT-7002 or MMT-7003) was inserted, wait 15 minutes before

connecting the iPro2.


- Make sure that the sensor insertion site is not bleeding before connection. If you find

blood on top of the sensor adhesive, do not connect the iPro2. This is to prevent body

fluids from getting into the connector of the iPro2. If blood gets inside the iPro2's

connector, it may not be properly cleaned out without damaging the connector, so the

iPro2 will have to be discarded.

- If bleeding occurs, apply steady pressure with a sterile gauze or cloth at the insertion

site until bleeding stops. After bleeding stops, attach the iPro2 to the sensor.

- If bleeding persists after three minutes, remove the sensor and discard. Insert a new

sensor in a different location.

• If body fluid comes into contact with the connector on a cleaning plug or the Dock, the

contaminated device must be discarded to prevent contamination of the iPro2.

• Do not allow fluids (including water, cleaning fluids, and disinfectants) on the iPro2's

connectors. Fluids can cause the connectors to corrode and may affect the iPro2's

performance.

Meters supported by CareLink iPro for uploading

For a list of supported meters, see your CareLink iPro Software User Guide.

Compliance information

The iPro2 and Dock comply with the United States Federal Communications Commission (FCC)

and international standards for Electromagnetic Compatibility. For the specific regulations and

test results for your area, please contact your local representative.

These devices comply with Part 15 of the FCC Rules. Operation is subject to the following two

conditions:

1 These devices may not cause harmful interference.

2 These devices must accept any interference received, including interference that may cause

undesirable operation. These standards are designed to provide reasonable protection against excessive radio frequency

interference and prevent undesirable operation of the device from unwanted electromagnetic

interference.

Interference from wireless devices

Common wireless consumer devices, such as cellular (mobile) phones or cordless phones, may

disrupt communication during iPro2 uploads to the computer. It is likely that other wireless

devices using similar frequency ranges will have a similar effect. This interference, however, will

not cause any incorrect data to be sent, and will not cause any harm to your iPro2 system.


To reduce the likelihood of data communication errors, you should relocate either the wireless

device or the iPro2 system devices. Testing conducted with several different cellular phones

suggests that interference will not be a problem if the phone is at least 30 centimeters (12 inches)

from the iPro2 system devices.

Key Notes:

• The reset button on the Dock is used to wake up (or activate) the iPro2 because it is shipped

in a special sleep mode. This is a one-time task. In the future, doing this will erase all sensor

data that is on the iPro2.

• Never connect an iPro2 to any device other than the Dock, sensor, or cleaning plug.

• Only use the cleaning plug for cleaning.

iPro2 CGM User Guide One-time device setup 7

One-time iPro2 activation

The iPro2 is shipped in a special sleep mode to protect its battery. You need to wake it up by

following this one-time procedure. This should be done a minimum of eight hours before your

first iPro2 patient setup.

CAUTION: Do not perform this procedure if you already have sensor data on the iPro2. If

you press the reset button while the iPro2 is connected to the Dock, all sensor data on theiPro2 will be erased. This procedure is only for activating the iPro2 for the first time.

1 Connect the small end of the USB cable to the Dock.

2 Connect the other end of the USB cable to the wall-powered adapter.

!!

3 Connect the wall-powered adapter into an electrical socket. The three lights on the Dock

will flash once, and then the white Dock power light will remain on, indicating that the Dock

is plugged in.

!!!!

!


4 Place the iPro2 into the Dock.

!!

The green charging light will start flashing.

NOTE: The red warning light may turn on if you do not immediately complete the nextsteps. This is normal because the iPro2 has not been activated. You can continue to

follow these instructions even if you see the red warning light.

5 Find the small hole on the back of the Dock, next to the USB cable. This is the reset button.

6 Insert the end of a small paper clip into the hole about 0.30 cm (1/8 inch). Push the reset

button once and release. The white Dock power light will flash . After a few seconds,

the green light on the iPro2 will flash.

The iPro2 is now activated. It will never return to sleep mode.

7 Leave the iPro2 on the Dock to continue charging. During charging, the white Dock power

light will be on, and the green charging light will flash.

!


8 Allow up to eight (8) hours for the iPro2 to fully charge. Once the iPro2 is charged, the green

charging light on the Dock will stop flashing and will remain on. This means that the iPro2

is fully charged.

!

When charged regularly after each sensor use, the iPro2 will become fully charged in only

about 30 minutes.


Key notes about iPro2

• The reset button on the Dock is used to wake up (or activate) the iPro2 because it is shipped

in a special sleep mode. This is a one-time task. In the future, doing this will erase all sensor

data that is on the iPro2.

• Never connect an iPro2 to an unpowered Dock. Always make sure that the white Dock power

light is on before connecting the iPro2. If you connect the iPro2 to an unpowered Dock

while it contains patient data, there is a chance that the data could be erased.

Also, do not connect or disconnect the Dock from a computer or electrical outlet while the

iPro2 is connected to the Dock. This could also cause patient data on the iPro2 to be erased.

Key Notes:

• Use universal precautions when handling the sensor.

• Do not use IV Prep prior to sensor insertion. It can damage the sensor.

• If the Enlite™ sensor (MMT-7008) was inserted, wait five minutes before connecting the

iPro2. If a different sensor (MMT-7002 or MMT-7003) was inserted, wait 15 minutes before

connecting the iPro2. Use this time to give instructions to the patient.

• Before setting up any patients on iPro2, make sure that your clinic has completed the one-

time CareLink software and computer setup instructions in the previous chapter.

iPro2 CGM User Guide Patient setup 12

Preparing for study

Before the patient arrives in your office, make sure that all the necessary equipment and supplies

are available and ready.!

Materials needed for patient setup:

• Cleaning plug

• Alcohol swabs

• Gloves

• Serter

• Glucose sensor

• Sharps container

• iPro2, charged and disinfected. The green charging light on the Dock must be on (not

flashing) before you remove the iPro2 from the Dock.

• Patient Log Sheets

• Patient Consent Form

• Patient Instructions

• Clinic Equipment Log

• Occlusive adhesive dressing

• Optional: Clinic Checklist

NOTE: Use universal precautions when handling the sensor.


Wiping the iPro2 with alcohol before a patient study

The iPro2 is intended for multiple patient use. Follow this procedure before each patient use.

WARNING: If there is any body fluid inside the connector, the iPro2 must be discarded. Donot discard the iPro2 in a medical waste container. The iPro2 contains a battery which mayexplode upon incineration. Dispose of the iPro2 according to the local regulations for

battery disposal (non-incineration). See Precautions for additional information.

1 While wearing gloves, attach the cleaning plug to the iPro2 to make sure that fluids do not

contact the iPro2's connector. Fluids can cause the connector to corrode and affect the

iPro2's performance.

CAUTION: Do not twist the cleaning plug while it is attached to the iPro2. This will

damage the iPro2.

2 Wipe the iPro2 with an alcohol swab or rinse with alcohol.

3 Disconnect the cleaning plug from the iPro2 by gently squeezing the arms of the cleaning

plug.


CAUTION: The o-rings on the cleaning plug have lubricant to help make a water-tightseal with the iPro2. This lubricant wears off after approximately 30 uses. At that time,

the cleaning plug must be discarded. Keep only one unwrapped cleaning plug at hand,so that you can keep track of its use and will know when to unwrap a new cleaningplug.

Tips for a successful patient study

• Keep the sensor hydrated and fully inserted throughout the study:

- Make sure to follow the sensor insertion instructions carefully.

- Choose a good sensor insertion site.

- Use the proper angle for insertion.

- Apply an adhesive dressing over the sensor and iPro2.

• If you see gaps in sensor data, it could be caused by any of the following reasons:

- The sensor was partially removed during the study, which means that no data was being

collected for that period of time.

- The iPro2 lost its connection with the sensor. If the iPro2 is disconnected from the sensor

and then reconnected during the study, it will continue recording. However, there will

be a gap in the sensor data. The length of the gap depends on how long the iPro2 was

disconnected.

- The sensor was not continuously hydrated while connected to the body. It is possible

for the sensor to lose hydration and then regain it, even if it does not pull out.

- CareLink iPro does not have good BG meter readings within 12 hours of each other to

calibrate all of the sensor data.

• Emphasize to the patient, ideally by using a Patient Instructions Sheet, the importance of

following instructions for blood glucose testing throughout the study. Patients should

complete at least four BG meter readings per day to avoid data gaps. If a patient does

not record accurate BG meter readings frequently enough, CareLink iPro will not have

enough BG meter readings to fully calibrate the sensor data. This can cause gaps in data on

the patient's reports. CareLink iPro needs at least one BG meter reading within an expected

range every 12 hours. Erroneous BG meter readings may be ignored by CareLink iPro and

may stop the sensor plot until the next good BG meter reading.

• Make sure that your patient tests blood glucose at least one hour after the iPro2 is connected

to the sensor. The iPro2 takes one hour to start up a sensor. If the patient does the first BG

meter reading too soon, sensor data will not be available for calibration. Therefore, the

sensor trace in the reports will begin at the time of the next BG meter reading. This will be

apparent in CareLink reports because the data will begin later than you expect.

• Make sure that the patient does another BG meter reading two hours after the first one.

This BG meter reading is a backup, in case the first BG meter reading was a few minutes

too early.


• Mid-study upload: Uploading sensor data from an iPro2 clears the data from the iPro2. The

first upload will be shown as its own study in CareLink iPro. When the iPro2 is reconnected

to the sensor, it will begin the 1 hour start up again and start a new study, assuming that

it also has enough charge to start a new study. You cannot combine two separate uploads

into one set of reports in CareLink iPro.

• Do not change the sensor during the study. The iPro2 will keep recording, but the values

on the second sensor will vary widely for many hours because the iPro2 will not properly

start the second sensor. For the best results, upload data after each sensor use.

Where to insert the Enlite sensor

This section contains important information about how to select a sensor insertion site when

using an Enlite™ sensor (MMT-7008). If you are inserting a different sensor (MMT-7002 or

MMT-7003), see the insertion sites described in the User Guide for the sensor or Serter.

WARNING: The sensor may affect patient medical conditions or medications. Bleeding,

swelling, irritation and/or infection at the insertion site are possible risks associated withinserting the sensor and sometimes result from improper insertion and maintenance ofinsertion site. Please discuss these conditions, medications and/or reactions with patients

before using the sensor.

Ask your patient about sleeping position and about his or her normal daily routine. Does the

patient exercise or do a lot of bending or lifting at work? What kind of clothing does the patient

normally wear? Are there other activities that could disturb a sensor site, such as prolonged

sitting in a driving position in a car? Choose a site that will be protected.

The clinical trials of Enlite sensor accuracy have been based on sensors inserted in the abdominal

and upper buttock areas.

Best locations for sensors:

• Abdominal area, including the front, sides, and back of the body

• Upper buttock area

• Areas with firm skin

Do not insert the sensor in:

• Frequently used injection or infusion sites.


• The 5.0 cm (2 inch) area around the patient's navel.

• Sites where clothing rubs the patient's skin or limits movement.

• Sites where clothing is restrictive, such as the belt line.

• Areas with tough skin or scar tissue.

• Body sites that the patient moves frequently.

• Sites on the patient's body that have minimal fatty tissue.

• Sites that will be pressed against the patient, such as the side he or she sleeps on.

• Sites on the patient's body where the fat is hard or solid.

CAUTION: Never insert the sensor within 5.0 cm (2 inches) from a pump infusion setinsertion site or within 7.5 cm (3 inches) from a manual injection site.

How to prepare the insertion site

1 Ask the patient to stand.

2 Clean the insertion site with alcohol and allow to air dry.

NOTE: Do not use sticky skin preparation solutions before inserting the sensor. A stickyintravenous (I.V.) preparation solution may be used after the sensor is inserted, and before

applying an occlusive adhesive dressing, to help the adhesive stick to the patient's skin.

Always refer to the instructions that came with the glucose sensor and Serter.

Inserting the Enlite sensor

This procedure shows you how to insert the Enlite Sensor (MMT-7008) using the Enlite Serter

(MMT-7510). If you are using a different sensor (MMT-7002 or MMT-7003), use the insertion

instructions in the sensor user guide.

CAUTION: Healthcare professionals and caregivers should use universal precautions whenhandling the sensor.

1 Wash your hands thoroughly.

2 Put on gloves.

3 Open the sensor package.


4 Remove the pedestal from the package. Place the pedestal on a flat surface.

5 Push the Serter down onto the pedestal until the base of the Serter sits flat on the table.

6 To detach the Serter from the pedestal, place two fingers on the pedestal arms and slowly

pull the Serter straight up. Do not detach the pedestal from the Serter in mid-air, as this

might damage the sensor.

WARNING: Never point a loaded Serter toward any body part where insertion is notdesired.

7 Place the base of the Serter flat against the patient's insertion site.

WARNING: The Serter injects sensor upon button release.

Adhesive tab

Sensor connectors

13 Make an entry on the Clinic Equipment Log and the Patient Log Sheet. Make sure to write

down the serial number (SN) of the iPro2, the patient’s name or ID, and the date that you

placed it on the patient.

14 You now need to wait at least five minutes before connecting the iPro2, to allow the sensor

to become hydrated with interstitial fluid. Take this time to brief your patient on what to

do when he or she goes home.

Briefing the patient

The patient must receive detailed instructions on wearing the sensor and iPro2, study

compliance, meter use and maintaining a log sheet. Ideally, provide the patient with a Patient

Log Sheet and a Patient Instructions Sheet. Go over the items listed on each of the documents

and make sure that your patient understands his or her responsibilities to ensure a successful

study.


Key points:

• Wear the iPro2 continuously while following normal daily activities.

• Record meals, blood glucose, exercise or strenuous activities, and medications on a Patient

Log Sheet.

• Keep the Patient Log Sheet accessible at all times so that information can immediately be

written down after each event. Record the time and date within five minutes of each BG

meter reading.

• Use the same glucose meter and the same lot of strips for the entire study.

• Do not let anyone else use the meter during the study.

• Do not use control solution during the study.

• Do not change any settings on the meter during the study, even if a daylight savings time

change occurs.

• Take at least four blood glucose (BG) meter readings per day, such as before each meal and

before bed.

• Take the first BG meter reading at least one hour after leaving the office, and another about

two hours after the first one.

• Only BG values between 2.2 and 22.2 mmol/L (40 and 400 mg/dL) will be used for

calibration. If a meter reading is outside of this range, it does not count, and another BG

meter reading will be needed when the patient's blood glucose is within the range.

CAUTION: The patient must return the iPro2 to the clinic within 10 days of the end of the

study. After 10 days, if the iPro2 is not connected to a powered Dock, the iPro2 battery maylose its charge, and all data on the iPro2 could be lost. Make sure to schedule the patient's

return of the iPro2 well within this time period.

What to do while briefing the patient

1 Give the patient the materials they need, including at least one Patient Log Sheet and a

Patient Instructions Sheet.

2 On the Patient Log Sheet, write the patient's name, iPro2 serial number, meter brand, meter

ID, and the times for the first two BG meter readings.

3 Make sure that the patient's blood glucose meter has a good battery that will last for the

entire length of the study.

4 Check the date and time on the blood glucose meter.

Meter use

Instruct the patient that BG meter readings are required to calibrate the sensor data, and that

for successful study data, the patient must follow these guidelines for meter use.

First day

The patient must do three blood glucose (BG) meter readings on the first day at these times:


• At least one hour after you connect the iPro2 and the patient leaves the office (but not any

sooner than one hour). Write this time on the front of the Patient Log Sheet.

• Two hours after the first BG meter reading (three hours after the iPro2 is connected)

• Once more before midnight

Remaining days

• For the remaining days of the study, collect at least four BG meter readings per day,

preferably before breakfast, lunch, dinner, and bedtime.

• The patient should do at least three BG meter readings on the last day before the sensor is

removed.

Care and wearing instructions

The patient can shower and swim without removing the iPro2 or sensor. The iPro2 and sensor

are water-tight for up to 30 minutes, up to a depth of 2.4 meters (8 feet). There is no time limit

for swimming on the surface of the water or showering.

The patient should periodically check the sensor site to ensure that the sensor and iPro2 are

tightly connected, that the sensor is fully inserted and that there is no bleeding or irritation at

the sensor site.

• If the sensor is partly pulled out, attempt to gently push it back into place.

• Remove the sensor if there is redness, pain, tenderness, or swelling at the site. The patient

should notify the physician’s office if experiencing any of these symptoms. Insulin should be injected at least 7.5 centimeters (3 inches) away from the sensor insertion

site, and insulin pump infusion should be at least 5 centimeters (2 inches) from the sensor

insertion site.

The iPro2 must be removed (but the sensor can be left in) prior to an x-ray, CT scan or MRI.

Simply reconnect the iPro2 afterward.

Make sure that the patient can return the iPro2 to the clinic well within 10 days of the end of

the study. After 10 days, if the iPro2 is not connected to a powered Dock, the iPro2 battery may

lose its charge, and all data on the iPro2 could be lost.

Preparing to connect the iPro2 (after briefing the patient)

1 If bleeding has occurred:

a. When bleeding stops, attach the iPro2 to the sensor.

CAUTION: If bleeding does NOT stop, do NOT connect the iPro2 to the sensor.

2 If bleeding does not stop after three minutes, do the following:

a. Remove the sensor and discard.

b. Reapply pressure using a sterile gauze or cloth until the bleeding stops.

c. Insert a new sensor in a different location.


Connecting the iPro2 to the sensor

Important: The iPro2 must be fully charged and cleared of data before connecting to a

sensor. You can verify this by connecting the iPro2 to the Dock. When you connect the iPro2

to the Dock, if the green charging light is on (not flashing), as shown below, the iPro2 is fully

ready to use.

!

1 If the Enlite™ sensor (MMT-7008) was inserted, make sure that it has been at least five

minutes since you inserted the sensor. If a different sensor (MMT-7002 or MMT-7003) was

inserted, make sure that it has been at least 15 minutes.

2 Touch the end of the inserted sensor to prevent it from moving during connection.

3 Hold the iPro2 as shown. The flat side of the iPro2 should face the skin.

NOTE: Overtape is not shown in the following steps.

4 Push the iPro2 onto the sensor until the sensor's flexible side arms snap into the notches

on the iPro2. If the iPro2 is properly connected, and if the sensor has had enough time to

become hydrated, within 10 seconds the iPro2's green light will flash six times. The flashing

takes about 10 seconds.

5 If the iPro2's green light flashes, then the sensor is fully hydrated and the iPro2 has

successfully started the study.

6 If the iPro2's green light does not flash, and the Dock displayed a solid green charging light

before you removed the iPro2 from it, then the sensor is not fully hydrated. You can

do either of the following:


a. If the Enlite™ sensor (MMT-7008) was inserted: remove the iPro2 from the sensor, wait

five minutes, and then try connecting the iPro2 again. This can be repeated every five

minutes until the sensor is hydrated.

If a different sensor (MMT-7002 or MMT-7003) was inserted, remove the iPro2 from the

sensor, wait 15 minutes, and then try connecting the iPro2 again. This can be repeated

every 15 minutes until the sensor is hydrated.

b. Remove the sensor from the patient’s body and insert a sensor in a new site on the

body.

If the Enlite™ sensor (MMT-7008) was inserted, wait five minutes for the new sensor to

become hydrated before connecting the iPro2 again.

If a different sensor (MMT-7002 or MMT-7003) was inserted, wait 15 minutes for the new

sensor to become hydrated before connecting the iPro2 again.

7 Cover the iPro2 with the Enlite sensor's adhesive tab.

8 [Optional]: Apply an occlusive adhesive dressing over the iPro2 and the sensor.

Tip: When applying the adhesive dressing, secure the sensor firmly but comfortably, and

secure the iPro2 loosely to allow some movement.

Important: If the sensor is pulled out by more than a millimeter, the iPro2 will stop collecting

data until the sensor is pushed back in place. When the sensor is pushed back in, the iPro2

will start collecting data 30 minutes later.

Disconnecting the iPro2 and removing the sensor

Disconnecting the iPro2

1 Put on gloves.

2 Carefully remove any adhesive dressing from the iPro2 and sensor assembly.

3 Hold iPro2 as shown, and pinch the flexible side arms of the sensor between your thumb

and forefinger. Do not twist the iPro2 relative to the sensor.

4 Gently pull the iPro2 away from the sensor assembly.

Removing the sensor

While wearing gloves, gently lift the sensor's adhesive tape away from the patient’s body to

remove the sensor. Place the sensor in a bio-waste container.


Cleaning the iPro2

The iPro2 is intended for multiple patient use. Always clean and disinfect the iPro2 before

connecting it to the Dock. The Dock cannot be disinfected.

WARNING: If there is any body fluid inside the connector, the iPro2 must be discarded. Donot discard the iPro2 in a medical waste container. The iPro2 contains a battery which may

explode upon incineration. Dispose of the iPro2 according to the local regulations forbattery disposal (non-incineration). See Precautions for additional information.

1 While wearing gloves, attach the cleaning plug to the iPro2 to make sure that fluids do not

contact the iPro2's connector. Fluids can cause the connector to corrode and affect the

iPro2's performance.

CAUTION: Do not twist the cleaning plug while it is attached to the iPro2. This willdamage the iPro2.

CAUTION: The o-rings on the cleaning plug have lubricant to help make a water-tight

seal with the iPro2. This lubricant wears off after approximately 30 uses. At that time,the cleaning plug must be discarded. Keep only one unwrapped cleaning plug at hand,so that you can keep track of its use and will know when to unwrap a new cleaningplug.

2 If there is adhesive residue on the iPro2, you can remove it with Detachol® adhesive remover

between each patient use.

3 Dampen a clean cloth with a mild liquid soap solution. Wipe the outside of the iPro2.


4 Rinse the iPro2 under warm tap water.

5 Apply three to four drops of a quaternary ammonium compound disinfectant (for

example, Cavicide®) on a clean, dry cloth and wipe the iPro2.

6 Hold the cleaning plug and wipe the iPro2 with 70% isopropyl alcohol.

7 Disconnect the cleaning plug from the iPro2 by gently squeezing the arms of the cleaning

plug.

8 Place the iPro2 on a clean, dry, non-shedding cloth and air dry completely.

!

If you do not see the white Dock power light, the Dock may have insufficient power to

operate. If it is the only device connected, try plugging the Dock into a different USB port

directly on the computer. Not all USB ports may get sufficient power for the Dock to operate.

You can also connect the Dock to the computer using a USB hub. However, if the white

Dock power light does not turn on, then try using a powered USB hub, which has its own

electrical plug that is connected to an electrical socket.

CAUTION: Never connect an iPro2 to an unpowered Dock. Always make sure that the

white Dock power light is on before connecting the iPro2. If you connect the iPro2

to an unpowered Dock while it contains patient data, there is a chance that the datacould be erased. Also, do not connect or disconnect the Dock from a computer or

electrical outlet while the iPro2 is connected to the Dock. This could also cause patientdata on the iPro2 to be erased.


5 When instructed by CareLink iPro, connect the iPro2 to the Dock.

!!

CAUTION: Do not connect more than one Dock to the computer at one time. Only

connect the iPro2 associated with the opened patient record to the Dock.

The three lights on the Dock will flash once when you connect the iPro2. Then the green

charging light on the Dock will start flashing . This indicates that the iPro2 contains

data that needs to be uploaded (or that the iPro2 is charging).

!

• Keep extra Patient Log Sheets and other iPro2 supplies in an organized cabinet.

iPro2 CGM User Guide System maintenance 32

Cleaning the iPro2

The iPro2 is intended for multiple patient use. Always clean and disinfect the iPro2 after removing

it from a patient. Make sure to connect the cleaning plug to the iPro2 before cleaning. For

complete instructions, see Cleaning the iPro2 on page 27.

Cleaning the Dock

The Dock cannot be disinfected. This procedure is for general cleaning as required, based on

physical appearance.

WARNING: Always clean the iPro2 after removing it from the patient and before attaching itto the Dock. If the Dock connector comes in contact with blood, the Dock must be discardedbecause the Dock's connector cannot be disinfected. Dispose of the Dock according to the

local regulations for electronic devices.

CAUTION: The Dock is not water-tight. Do not immerse in water or any other cleaningagent. Do not allow liquid to come in contact with the Dock's connector. Repeat exposure to

liquid could damage the connector and affect the performance of the device. If liquid comesin contact with the connector, allow the Dock to air dry before proceeding with the cleaning

instructions.

1 Disconnect the Dock USB cable from the computer or wall-powered adapter.

2 Disconnect the Dock from the USB cable.

3 Use a damp cloth with mild cleaning solution, such as Dial® Dishwashing detergent, to clean

any dirt or foreign material from the outside of the Dock. Never use organic solvents such

as paint thinner or acetone to clean the Dock.

4 Place the Dock on a clean, dry cloth and allow it to air dry completely.

5 When the Dock is completely dry, you can reconnect it to the computer or wall-powered

adapter with the USB cable.

Components that cannot be cleaned

You cannot clean the following components of the iPro2 system:

• Cleaning plugs (discard each cleaning plug after 30 uses)


• Wall-powered adapter

• Dock USB cable

Charging the iPro2 between studies

Charge the iPro2 in the Dock. The Dock can be connected to the computer or to the wall-

powered adapter, which lets you use a regular power outlet for charging. While the iPro2 is

charging, the green charging light on the Dock is flashing, as shown:

!

Between patient studies, the iPro2 should take less than 30 minutes to reach a full charge. When

the iPro2 is fully charged, the green charging light on the Dock remains on:

!

CAUTION: If the green charging light continues to flash and never turns solid, this indicates

that the iPro2 contains patient data that you have not uploaded. You cannot use the iPro2for another study until you upload the data. If you need to clear the data withoutuploading it, you can perform a reset. For details, see Resetting the iPro2 on page 42.

Always leave the iPro2 connected to a powered Dock when not in use. This maintains the life

of the iPro2 battery and keeps the iPro2 ready for the next patient study.

If your clinic has only one iPro2, you can leave the Dock connected to the computer and connect

the iPro2 to the Dock when not in use. The computer supplies enough power to charge the

iPro2, as long as the computer is on and the white Dock power light is on .

!

If you have multiple iPro2s, you can use the wall-powered adapters to keep them charged at

power outlets, and leave one Dock connected to the computer at all times so that it is ready to

upload data.


Tip: To extend the life of your Docks, mark your calendar to periodically exchange the Dock that

you have connected to the computer with a Dock that is connected to an electrical socket. The

Dock connected to the computer gets the most use, and the connector can wear out over time.

!! !

Storage and organization tips

When not in use, store the iPro2 on the Dock and keep the Dock plugged in, so that the iPro2

remains charged. Otherwise, the iPro2 battery could become damaged.

You can organize your other iPro2 supplies in a small drawer organizer, such as the one shown

here. These are some of the items that you will want to keep on hand and ready for the next

patient:

• Serter

• Glucose sensors

• Occlusive adhesive dressings

• Alcohol swabs

• Gloves

• Documents and forms, including:

- Patient Log Sheets

- Patient Consent Forms

- Patient Instructions Sheets

- Clinic Equipment Log sheets

- Clinic Checklists

- A printed copy of this User Guide

• Cleaning plugs

• Gauze pads


• Quaternary ammonium compound, such as Cavicide®

Troubleshooting

This appendix contains troubleshooting information for the iPro2 CGM System. Please refer to

these instructions before contacting your local representative.

Troubleshooting reference

Problem Possible causes What to do

I connected the iPro2 tothe sensor, and the iPro2did not flash after 10seconds.

Either the sensor is notadequately hydrated, theiPro2 is not connectedproperly, or the iPro2 isnot ready to begin a study.

Did you take the iPro2 directly from a poweredDock, and did the Dock display a solid green

charging light?

• If yes, then the iPro2 may not be connectedproperly, or the sensor may not be fullyhydrated. Disconnect and reconnect the iPro2.If this does not work, wait another five minutesand then connect the iPro2 to the sensoragain. If the iPro2 still does not flash, waitanother five minutes and try again. In somecases, it can take up to two hours for the sensorto become hydrated.

If the iPro2 still does not flash after two hours,you can remove the sensor and insert a newsensor in a different site on the body.

• If no, or if you are not sure, the iPro2 may notbe fully charged, or may still contain data froma previous study. In these cases, the green lightwill not flash when connected to the sensor.

Disconnect the iPro2 from the sensor. Clean anddisinfect it (see Cleaning the iPro2 on page 27),and then connect it to the Dock. If the greencharging light on the Dock turns solid after twominutes, the iPro2 is ready to start a study on anew patient. If not, the iPro2 needs to becharged or still contains patient data from theprevious study.

If these steps do not work, use the Dock to resetthe iPro2. For instructions, see Resetting the iPro2 onpage 42.

iPro2 CGM User Guide Troubleshooting 37



The iPro2 has beenconnected to the Dockwith adequate power fortwo to three hours, but thegreen charging light keepsflashing.

!

The iPro2 most likelycontains data that has notbeen uploaded.

• Check the Clinic Equipment Log or Patient LogSheets to find out which patient's data was lastcollected. Open CareLink iPro and check to seeif a study was uploaded for the dates on the logsheet. If there is no study, upload the iPro2 intothat patient's record in CareLink iPro. CareLinkiPro clears the data off of the iPro2 as part ofthe upload process. You must then wait for thegreen charging light on the Dock to turn solidbefore the iPro2 is ready to use for the nextpatient.

• If you are unable to identify which patient's datais still on the iPro2, or if you are unable toupload the iPro2 successfully, you may need toreset the iPro2. For instructions, see Resettingthe iPro2 on page 42.

I connected the iPro2 tothe Dock and no lightscame on.

The Dock may not beconnected to thecomputer, or it may nothave sufficient power. Thewhite Dock power light

must be on before

If the red warning light continues to turn on, or ifthe iPro2 pins are damaged or corroded, contactyour local representative. It may be time to replacethe iPro2.


Checking the iPro2 connector pins

If the troubleshooting reference advises you to check the connector pins of the iPro2, use the

following image to assist you. This image is an example of how the connector pins should look.

Look inside the iPro2’s connector to make sure that the pins are not damaged or corroded. If

the connector pins are damaged or corroded, the iPro2 cannot communicate with the Dock or

CareLink iPro. Contact your local representative. It may be time to replace the iPro2.

Also look for moisture inside the connector. If you see any moisture, allow the iPro2 to dry for

at least one hour. Moisture inside the connector could cause the iPro2 to not work properly, and

could cause corrosion and damage over time.

To help prevent damage to the pins:

• Make sure to carefully connect the cleaning plug or sensor to the iPro2.

• Do not twist or bend the cleaning plug or sensor when connecting to the iPro2. For instructions on how to properly clean the iPro2 using the cleaning plug, see Cleaning the

iPro2 on page 27. For instructions on how to properly connect the iPro2 to a sensor, see

Connecting the iPro2 to the sensor on page 23.

B

Enlite Sensor performance

In Vivo performance

The performance of the glucose sensor was assessed using post-hoc analysis of a 2-month

study1 with a prospective correlational design without controls. The sensor data from a total of

64 subjects contributed to the analysis. Subjects had type 1 diabetes and were 18–75 years of

age. People with tape allergies, skin abnormalities, and some serious concomitant conditions

were excluded from enrollment.

Subjects wore two Enlite sensors attached to the abdomen and buttock areas over two periods

of seven days. Sensors that failed before the end of day 7 were removed and not replaced.

Subjects tested their capillary blood glucose level a minimum of 4 times per day using a

commercially available home blood glucose (BG) meter.

The accuracy of the sensor using the iPro2 retrospective algorithm was the primary efficacy

variable. The raw sensor data and the BG meter readings were post-processed using the iPro2

retrospective algorithm to generate glucose values. To assess sensor accuracy, the retrospectively

calibrated glucose values provided by the sensor (sensor values) were compared to the glucose

values provided by the BG meter reference values (also called self-monitoring of blood glucose

or SMBG).

Results

Site comparison

Sensors were used in both abdominal and buttock sites, and showed similar performance. The

overall mean and median absolute relative difference (MARD) was calculated for sensors located

Clarke error grid analysis

The Clarke Error Grid was used to assess the clinical relevance of the differences between the

iPro2 readings and the comparative blood glucose meter measurements. The Clark Error Grid

separates paired observations into five zones (A, B, C, D, and E). The presence and severity of

possible treatment error based on interstitial glucose evaluated by the sensor is defined by the

following zones:


Zone Description

A Clinically accurate, would have led to correct treatment decisions.

B Would have led to benign decisions or no treatment.

C Would have led to over-correction of normal glucose levels.

D Failure to detect a glycemic level that might have required action by the patient to correct.

E Erroneous data point. If acted upon, could have been harmful.

In order to evaluate differing levels of accuracy at various blood levels, summary statistics (n, %)

are calculated in each of the five zones. Summary statistics for each of the zones are reported

for each stratum of the referenced values.

Temporally paired glucose measurements from the iPro2 and reference meter BG were plotted

as Clarke Error Grid (CEG) scatter plots. A total of 6582 (97.7%) of paired points were in zones A

and B of the Clarke Error Grid. These results of both algorithms exceed the threshold for clinical

acceptability.

Sensor Life

After calibration, 87.7% of sensors operated until they were removed on or after the seventh day

of wear. Five sensors out of 261 did not calibrate properly. Finally, four sensors were removed

after first calibration event because the companion sensor was removed.

Interference

In vitro and in vivo testing suggests that usual pharmacologic levels of acetaminophen and

ascorbic acid have a minimal effect on the function of the iPro2 system. In vitro testing suggests

that normal physiological levels of uric acid do not affect sensor function. The impact of oral

hypoglycemic agents, lipids, bilirubin and other potential interfering substances have not been

studied.

Limitations

Since the iPro2 system requires calibration using a blood glucose value obtained from a home

glucose meter, any inaccuracy in value obtained from the reference meter will affect the accuracy

of the value calculated by the iPro2 system. Also, since the sensitivity of the sensor may

change, failure to recalibrate the sensor by taking BG meter readings at least three timesdaily may result in inaccurate glucose readings.

In vitro testing has indicated that the iPro2 may record inaccurate glucose readings during

exposure to electromagnetic fields of 3 V/m or stronger. Therefore, the use of the iPro2 systemin close proximity to strong electromagnetic sources, such as medical imagingequipment, television transmitters, high-voltage power lines and high-power radio

transmitters, is not recommended.

Sensor performance (MMT-7002,MMT-7003)

In Vivo performance

The performance of the glucose sensor was assessed using post-hoc analysis of a 10-month

study1 with a prospective correlational design without controls. The sensor data from a total of

132 subjects contributed to the analysis. Subjects had type 1 diabetes and were 7–75 years of

age. People with tape allergies, skin abnormalities, and some serious concomitant conditions

were excluded from enrollment.

Subjects wore the Guardian REAL-Time System, a stand-alone personal continuous glucose

monitoring device, for a period of approximately 42 days. Once the investigator confirmed that

the subject was eligible for the study phase, eligible subjects were scheduled to wear a minimum

of 4 sensors for 6 days each over the next 4 weeks. Raw uncalibrated sensor data was

collected. Sensors that failed before the end of day 6 were removed and not replaced. Subjects

tested their capillary blood glucose level a minimum of 4 times per day using a commercially

available home blood glucose (BG) meter.

The accuracy of the sensor using the iPro2 retrospective algorithm was the primary efficacy

variable. The raw sensor data and the BG meter readings were post-processed using the iPro2

retrospective algorithm to generate glucose values. To assess sensor accuracy, the retrospectively

calibrated glucose values provided by the sensor (sensor values) were compared to the glucose

values provided by the BG meter (reference values).

Mean absolute relative difference (MARD or MAD%)

Adult Subjects

Using the iPro2 algorithm, the MARD for adult subjects was 11.0%, with a standard deviation

(SD) of 11.28. The lowest MARD of 7.8% (7.53) occurred in the 13.38-22.20 mmol/L

(241-400 mg/dL) range. The highest MARD of 18.6% (18.91) occurred in the 2.22-4.44 mmol/L

Precision

NOTE: In vivo precision studies have not been performed to date and therefore results maydiffer due to matrix effects.

Precision of the iPro2 system was evaluated in vitro by calibrating sensors in solutions with known

glucose concentrations (measured using a YSI Glucose Analyzer) and then repeatedly performing

measurement (at least 10 times) in solution with concentrations across the operation range. The

average coefficient of variation was 5.06%. The average coefficients of variation for the specific

glucose concentrations that were utilized for this evaluation are provided in the table below.

Glucose concentration Average coefficient of variation

2.77 mmol/L (50 mg/dL) 9.2%

8.32 mmol/L (150 mg/dL) 2.9%

13.88 mmol/L (250 mg/dL) 2.3%

16.65 mmol/L (300 mg/dL) 5.5%

Interference

In vitro and in vivo testing suggests that usual pharmacologic levels of acetaminophen and

ascorbic acid have a minimal effect on the function of the iPro2 system. In vitro testing suggests

that normal physiological levels of uric acid do not affect sensor function. The impact of oral

hypoglycemic agents, lipids, bilirubin and other potential interfering substances have not been

studied.

Limitations

Since the iPro2 system requires calibration using a blood glucose value obtained from a home

glucose meter, any inaccuracy in value obtained from the reference meter will affect the accuracy

of the value calculated by the iPro2 system. Also, since the sensitivity of the sensor may

change, failure to recalibrate the sensor by taking BG meter readings at least three times

daily may result in inaccurate glucose readings.


In vitro testing has indicated that the iPro2 may record inaccurate glucose readings during

exposure to electromagnetic fields of 3 V/m or stronger. Therefore, the use of the iPro2 systemin close proximity to strong electromagnetic sources, such as medical imaging

equipment, television transmitters, high-voltage power lines and high-power radiotransmitters, is not recommended.

Where P is the maximum output power ratingof the transmitter in watts (W) according tothe transmitter manufacturer and d is therecommended separation distance in meters(m).

Field strengths from fixed RF transmitters, asdetermined by an electromagnetic sitesurveya, should be less than the compliancelevel in each frequency rangeb.

Interference may occur in the vicinity ofequipment marked with the followingsymbol:

NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption, andreflection from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and landmobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoreticallywith accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic sitesurvey should be considered. If the measured field strength in the location in which the iPro2 CGM system isused exceeds the application RF compliance level above, the iPro2 CGM system should be observed to verifynormal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the iPro2 CGM system.

b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Logbook - A screen in CareLink iPro that lets you manually enter events such as BG meterreadings, meals, exercise, and medication taken, so that these events show up on reports. TheLogbook also displays BG meter readings, and possibly other events, that you upload from asupported blood glucose meter into CareLink iPro.

Mean Absolute Difference % (MAD%) - Represents the level of accuracy in calibration of thesensor to BG meter readings. The lower this number, the greater the calibration accuracy. MAD% is calculated by taking the difference between closely occurring pairs of sensor glucose andBG meter readings, dividing by the BG meter reading and then averaging across all pairs.

Mean Absolute Difference (MAD) - Represents the level of accuracy in calibration of the sensor toBG meter readings. The lower this number, the greater the calibration accuracy. MAD iscalculated by taking the difference between closely occurring pairs of sensor glucose and BGmeter readings and then averaging across all pairs.

Meter - a medical device for determining the approximate concentration of glucose in the blood.A small drop of blood is placed on a disposable test strip, which the meter reads and uses tocalculate the blood glucose level. The meter then displays the level in mg/dL or mmol/L.

Serter - The Serter is an aid for the insertion of a Medtronic Diabetes glucose sensor.

Study - The period of time that a patient wears a glucose sensor and iPro2. This word also refers toan upload of glucose sensor data from an iPro2 into CareLink iPro, along with any meter uploadand Logbook entries for that iPro2 upload. Each study has its own set of reports.
